From memory the 1001 has a brushless AC motor, so no carbon brushes to check. As far as capacitors going in foot controls, it's usually the old line filter capacitors (filter out unwanted radio frequencies) that go, and they are not found in your model foot control. Also, when they do go, the machine usually runs flat out rather than not at all. If you're concerned about wiring you can check continuity with a multimeter. I'd be swapping out the foot control and if that fails, swap out the l-print (power print). Might be a job for a tech.
